Answer:

Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don't know the perimeter, calculate it from the side length: p = 5s, where s is the side length.

Solve the quadratic equation 6x^2-13x-28=0 by factoring.

mixer [17]

First step to factor the trinomial, multiply the constant -28 with the leading coefficient 6.

So, -28 * 6 = - 168.

Next step is to breakdown -168 into two multiples so that their addition will result the coefficient of w= - 13.

So, -168 = -21 * 8.

And addition of - 21 and 8 will give - 13.

So, next step is to replace -13x with -21x + 8. Therefore,

6x² - 21x + 8x - 28 =0

(6x² - 21x) + (8x - 28 )=0 Make the group of two terms.

3x (2x - 7) + 4 (2x - 7) = 0 Take out the common factor from each group.

(2x - 7)(3x + 4) = 0 Again take out the common factor (2x -7).

So, 2x - 7 =0, 3x + 4 = 0 Set both the factor equal to 0.

2x = 7 , 3x = -4

So, $x= \frac{7}{2} , -\frac{4}{3}$

Hope this helps you !

Answer:

5 $\frac{7}{8}$

Step-by-step explanation:

You subtract all those distances from 22 to calculate the remaining distance.

22-4 $\frac{3}{4}$ = 17 $\frac{1}{4}$

17 $\frac{1}{4}$ -5 $\frac{1}{8}$ =12 $\frac{1}{8}$

12 $\frac{1}{8}$ -0=12 $\frac{1}{8}$

12 $\frac{1}{8}$ -6 $\frac{1}{4}$ =5 $\frac{7}{8}$

So the answer is 5 $\frac{7}{8}$

(Yes I did these in my head)

if leslie moves her money into an account that pays 8 percent compounded annually for 5 year(s), the amount of money that will a

aliina [53]

The value of an account at 8% compounded annually,
after 5 years have passed since your initial deposit, is

(the amount you originally put in) x (1.08)⁵ .

You didn't tell us how much Leslie invests at the beginning of the 5 years.
Whatever the amount is, it will become 46.9% greater in 5 years !
